What you’ll need to do is change the background color in either your style1.css, style2.css or style3.css located in the theme’s CSS folder. The stylesheet you use depends on which “skin” you’ve selected under Avisio Options e.g. “Default” = style1.css.

So you know each page has multiple background colors applied. By that I mean, you’ll find a background color for body; another for #wrapped_header; another for #wrapper_main; and so forth.
